The stpcide
driver supports the
STMicroelectronics STPC x86 SoC internal IDE controllers, and provides the
interface with the hardware for the
ata(4) driver. The driver
features DMA mode 2 and PIO mode 4 transfer speeds.
The 0x0002 flag forces the stpcide
driver
to disable DMA on chipsets for which DMA would normally be enabled. This can
be used as a debugging aid, or to work around problems where the IDE
controller is wired up to the system incorrectly.
ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)
The timings used for the DMA and PIO modes are for STPC Atlas and its siblings with their PCI clock configured at 33 MHz. Other speeds including the STPC Vega Ultra-IDE controller will need adjustments.
